' 5 Claims. (Cl. 139-212) UNITED STATES PATENT OFFICE This inventionrelates to loom shuttles and has particular reference to the provisionof means in the eye of the shuttle whereby the yarn or thread or weftbeing drawn from the shuttle at each pick in each direction,in thecourse of weaving a fabric, is caused at irregular intervals to have arufiied or fluffy or bunched effect in spots and accordingly thematerial or fabric being woven will be given a very different appearancethan that of the fabric woven by the use of a shuttle not provided withthe present invention.

The present invention consists broadly in roughening the side walls ofthe shuttle eye, or in applying to the walls of the eye, some hardened,roughened material such as emery, cement or the like, whereby when theyarn or thread is drawn through the eye, in the process of weaving, thesame will be ruliled or fiuifed in spots and accordingly such rulfled orfluffed spots will appear in the finished fabric.

In the present invention an abrasive material such as emery, or cementof some character, is positioned around the sides of the delivery eye ofthe shuttle in position to be engaged by the filling thread as itemerges from the eye. The construction and arrangement of the abrasiveis such that the short, loose fibers which are spun on the fillingadhere or catch on the ab- W rasive material and are caused to gatherinto a bunch or slub or fluff, along the thread. When such a slub orbunch is formed and has reached a certain appreciable size it pullsloose' from the abrasive or roughened formation on the walls of the eyeand amather slub is immediately started and eventually formed and as inthe first instance pulls away from the material, and this continuesuntil the filling on the bobbin is exhausted.

One form of embodiment of the present invention is shown in theaccompanying drawing, wherein corresponding reference numerals are usedto indicate corresponding parts in each of the views.

In the drawing:-

Fig. 1 is a top plan of the delivery end of the shuttle, including aportion of the bobbin car-' rying the filling thread, the portion of theshuttle about the eye being broken away and shown in section; and

Fig. 2 is a front-elevation.

In the drawing l indicates the shuttle having the usual bobbin llcarrying the thread I! which passes over the tension pad I3 under thecover 56 I4 and shield l5 through the eye IS, in the usual mariner inthe operation or pick of the shuttle across the loom.

In the present invention I have roughened in any desired manner the sidewalls I! of the eye or outlet I6, preferably by coating or lining saidwalls with an abrasive roughened material l8. The filling thread I2 inits passage through the eye l6 contacts and passes over the roughenedabrasive material on the left hand wall of the eye in the movement ofthe shuttle to the right 10 and over the abrasive material on the righthand wall in the passage of'theshuttle to the left.

As the thread passes over this roughened portion of the eye in theprocess of weaving there will be formed on the thread at intervals smallfiuffs or bunches of the thread as at IS. The thread passing over theabrasive material is caused to fluff or bunch at intervals and when acertain amount or size of fiuff is formed the same then pulls away fromthe abrasive material and passes on out of the eye and the formation ofanother fiufi or bunch is begun.

It will thus be seen that as this thread with the fluffs or bunchesthereon is woven into the fabric quite a difference in appearance willbe given to the fabric from that wherein the filling thread is not soacted upon.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States, is:

1.,A loom shuttle, a bobbin therein carrying yarn having loose fibres ornubs spun thereon, said shuttle having an eye or outlet through whichthe yarn passes, the walls of said eye being lined with an abrasivematerial over which the yarn passes, whereby in'the operation of weavingsaid nubs or loose fibres are formed into fiulfs or bunches at'intervalson the yarnl 2. A loom shuttle, a bobbin therein carrying yarn havingloose fibres or nubs spun thereon, 4 said shuttle having an eye oroutlet through which the' yarn passes, an abrasive material in said eyeover which the yarn passes, whereby in the operation of weaving saidnubs or loose fibres are formed into fiuffs or bunches at intervals onthe yarn.

3. A loom shuttle, a bobbin therein carrying yarn having loose fibres ornubs spun thereon, said shuttle having an eye or outlet through whichthe yarn passes, the opposite walls of said eye being coated with anabrasive material over which the yarn passes, whereby in the operationof weaving said nubs or loose fibres are formed into fiufis or bunchesat intervals on the yarn.

4 A loom shuttle, a 'bobbin therein carrying ing yarn having loosefibres or nubs spun thereon, said shuttle having an eye or outletthrough which the yarn passes, the opposite walls of said eye beingcoated with emery over which the yarn passes, whereby in the operationof weaving said nubs or loose fibres are formed into fiufis or bunchesat intervals on the yarn.
